I am trying to install the production release version 1.2.5-1 of ChimeraX on a fresh Debian ""Bullseye"". Unfortunately, neither the generic version, nor installation of any of the deb packages work. If you want, I can send you the details for all versions that I've tried. However, I thought, I rather give you the details for the Ubuntu 20.04 version, which should be closest to Debian ""Bullseye"". Trying to install the downloaded package as root results in the following error message: # apt install ./ucsf-chimerax_1.2.5-1_amd64.deb Reading package lists... Done Building dependency tree... Done Reading state information... Done Note, selecting 'ucsf-chimerax' instead of './ucsf-chimerax_1.2.5-1_amd64.deb' Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies:  ucsf-chimerax : Depends: libllvm10 but it is not installable E: Unable to correct problems, you have held broken packages. Debian ""Bullseye"" unfortunately has libllvm versions 9 and 11 in its repository, but not version 10: # apt search --names-only libllvm Sorting... Done Full Text Search... Done libllvm11/stable,now 1:11.0.1-2 amd64 [installed,automatic]   Modular compiler and toolchain technologies, runtime library libllvm9/stable,now 1:9.0.1-16.1 amd64 [installed,automatic]   Modular compiler and toolchain technologies, runtime library If you need more information, I would be happy to send it to you!
